AIRSHIP.

Application filed March 29, 1909, Serial No. 488,400.

To all 'H-ILOIH it iii-i5; concern:

Be it known'that, I, FLOHEXTIX BAHAUQT- insn. a citizen of the Republic of Switzerland. residing at San Francisco, in the count of iian Francisco and State of California, have invented certain new and use fol Improvements in Airships, of which the following is a specification.

My invention relatesto improvements in air-ships.

The object of my invention is to provide an airship which has great lifting power, and power of propulsion, as well as ease of dirigibility.

My invention consists in the novel'arrangement and combination of parts shown in the accompanying drawings, described in the following specification and claimed. in the appended claims. I

v Referring to said drawings, Figure 1 is a view of the rear portion of said air-ship, and Fig. 1 is a'riew of the front portion or said ship, the said figures comprising a complete side elevation of the same. Fig. 3 is a broken detail view of the steering propeller. F .2 is a transverse section of said. air-ship on an enlarged scale, and Fig. l is a side elevation of said steering propeller. Fig 5) is plan view of the interior drivingmechanism of said air-ship.

In the figures 1 indicates a gas-holderof cylindrical form,, pointed at its forward end. and supporting a structure or cabin :2, said cabin having the windows 3 for the illumination of the same. Vertical fans -tand side propellers 5 are centrally secured to revolnlile shafts 6, the side propellers being provided with hubs .3. Theshai'ts ti, to

.which fans -1- are attached are 'so placed that but half of the said fans, or a portion thereof, may be exposed without the structure 2 at one time while their revolution is taking place, the shafts (i being preferably placed in proximity to the wall of said structure and in line therewith. The shafts 6 are supported at their lower ends by the sustaining rods 7 in whiea they are turnable. The openings in which fans=-l-revolve are indicated by the numeral 4". A landing base 8 has rods 9 secured in the lower structure or rods '5, but so 21$. to permit the vertical movement of said rods 9, openings through the cross pieces intervening: being provided. the. lower ends of the springs inclosing said rods 9 being secured thereto, the springs being of greater diameter than Specification of Letters Patent.

the rods 9 and being indicated by the innmeral i0.

A steering propeller *2 with rover-ible blades i3 is situated at the forward coil of 5*. the ship. "he said blades 13 are pivoted at 13' the steering device bein' morrmted on drive shaft 20. Arms 21 extend {mm the aforesaid pivots 13' and are pivotmily connected by links to the collar 23: The 65 said collar 23 is slidahlc, bein slidably hated to shaft 20. the key on said shaft been; indicated by the numeral 2 Each side of lever 25 as shown in Fig. 2) is identical. 3. ing pivotally secured to the ring 25 loosely 1 .1) mounted in said collar in a suitable annular channel. the upper portion at said lever as secured to said ring 5 being preferably U-shaped, a handle depending therefrom as shown in said Fig. 3.

llach blade 1?, is provided with a pivot 33'. an arm 21. and a liulv 2"2 pivoted to theannular flange 23 on the colla 23. .Xe the rear end of the vessel. shaft H is pro'" l dwith gears 13 which engage gears it an 1T 83 in the following manner: Gears IT rt'l'iilSif oi two wheels mounted on the shafttL. all upper whe l eng ging the pinion 15. an" lower one the gear l6. whereby the rot of the shafts t? and the shafts connected t 35' propellers ll is accomplished, which hatter shafts extend. longitudinally through the interior of the said vesse 2! indicates a central longitudinal rhiaft having a gear positioned on the forward 99 end thereof as shown in Fig. li -l 37 is driven by the engine lit; and operates a transverse shaft earning a gear placed iu termediately tl :-reon. said gear being trolled by z clutch operated by lower ite-h 95 lever as shown. The ends of Said transverse shaft carry gears controlled by clutches operated by upper clutch lever 40 pivoted to arms 38 and 3!) asshown, {hen the gear placed intermedialely as inentimn d engages the gear on the end of shaft 25* as mentioned said central shaft is dritven. Said Shaft 29 carries gears 35 which opt-"sate gears o-l secured to shafts ll carrying g eats 323. which op rate gears 3'. and theen): 1 shafts 6. Additional power is provided by shafts 29' carrying gears 30 engaging gears 31 therefor and said shat'ts elfect the more: meat. of end propellers 11.

An) suitable belt or other connection Lana he provided forthe movement of shaft 2" by the front transverse l'evoluble shaftv By as its descent accomplished.

' side of said cabin, a plurality of propellers positioned below said fans a front steering changing the direction of the blades 13 by the use of the operating mechanism shown and described a change in he direction of the flight of the vessel may be accomplished.

The gas-holder 1 to be filled with gas for raising the vessel is preferably constructed of aluminum, though other suitable material may be used, aluminum being preferable owing to its strength and compara live lightness. The gas-holder l to be filled with gas for raising the vessel as mentioned has preferably the cylindrical shape shown in the drawings, though its shape may be modified without departing from the spirit of my invention Vertical fans 4 are intended for the forward movement of the vessel and side propellers 5 to assist in its upward movement. lly reducing the amount of gas in the gasholder through a -suitable openingvthercin provided with a suitable valve, the further upward 1novement of the vessel may be retarded as well The vessel is provided with a sharp prow, the front of the gas-holder being inclined downwardly and the front of the cabin being inclined upwardly, the inclined walls meeting centrally between the base of the vessel and its top. The lower structure 7 constitutes a stop for the base 8. The construction of the vessel permits ample space for the passengers and their effects.

Having thus described my invention what I, claim as new and desire to secure by'Letters Patent, is

1. In an air-ship the combination of a gasholder, a. cabin, a plurality of fans centrally secured to rcvoluble shafts on each side of said cabin, a plurality of propellers positioned below said fans, a front steeringwheel having centrally pivoted blades and rear propellers. 4

2. In an air-ship the combination of a gas-holder, a cabin, a plurality of fans centrally secured to revoluble shafts on-each wheel having centrally pivoted blades, slid able means connected to said blades for adjusting the same and rear propellers.

3. In an air-ship the combination of a gas-holder, a cabin, a plurality of fans centrally secured to revoluble shafts on each side of said cabin, a lurality of propellerspositioned below said fans a front adjustable steering wheel, rear propellers, a central longitudinal shaft, ashaft on each side of said central longitudinal shaft, gearing for the movement of said fans and propellers in operative C-HIIQCUOII with said shafts,

a transverse shaft carrying gearing for the revolution of said shafts clutch mechanism for throwing said transverse shaft in and out of gear. and a landing base provided with vertical lrods and springs for permittin; its upward movement on contact with the ground. V

4. In an air-ship the combination of a gas-holder, a cabin, a plurality of fans centrally secured to rcvoluble shafts on each side of said cabin, a plurality of propellers V positioned below said fans, a front steering wheel having adjustable blades, rear propellers, a landing base provided witlrvertical rods and springs for permitting its upward movement on contact with the ground,

and a lower structure secured above said secured above said'landing base for intcrcepting such upward movement.

In testimony whereof I athx my signature, in presence of two Witnesses.
